Abstract: A bone screw includes a head portion and shank portion. The shank portion includes a regularly outwardly expanding threaded portion.

Abstract: The present invention provides a vertebral implant comprising a wall forming two short sides (100, 101) and two elongated sides (102, 103) to define a generally elongated structure having a passageway (106) therethrough. At least one of the two elongated sides is resiliently compressible into the passageway, or resiliently expandable away from the passageway, under a force applied to the implant by movement of the spine into which the implant is placed. This resilient opposition to forces in the spine causes the device to want to return to its at-rest position, thereby aiding the spine in its return to a normal position after movement is relaxed, thereby aiding proper spine alignment. Preferably, the device comprises a flexible body having a generally loop-shaped configuration defined by the wall, wherein the wall material and thickness is selected so that the device has appropriate degrees of flexibility and strength.

Abstract: A method and apparatus provides a mask key that is used instead of mask data. In an embodiment of the present invention, a write mask key is generated by a memory controller and transferred to a memory device that uses the write mask key to determine whether to write a data value to a storage array. A plurality of decoders, an OR logic gate tree and a binary propagation tree is used to provide the write mask key that reduces latency while using the approximate same circuit area and allows for the use of standard software tools in an embodiment of the present invention. A plurality of log2 decoders is coupled to a plurality of OR logic gates in the OR logic gate tree.

Abstract: A removable spacing stabilizer for a jaw meter bus assembly having two pairs of generally parallel flat, elongated busses, each bus having a cantilevered second leg. The removable spacing stabilizer includes a generally planar member made from a generally rigid, non-conductive material. The planar member has a positioning slot for each of the bus cantilevered second legs. Whereby the planar member may be coupled to said jaw meter bus assembly with each bus cantilevered leg disposed in a positioning slot and whereby the bus cantilevered legs are held in a selected orientation.

Abstract: A reduced movement off-line inking device is shown. The reduce movement off-line inking device comprises an interference fit ink cartridge collar; and a substantially immovable ink cartridge support coupled to the interference fit ink cartridge collar; wherein the substantially immovable ink cartridge support comprises: a base member mounted upon a prober ring carrier; and a support arm member mounted to the base member, the support arm member coupled to the substantially immovable ink cartridge support.

Abstract: A secure content delivery system which is particularly useful for network distribution of electronic books includes a reader capable of storing encrypted text files downloaded from a content server such as a publisher's server. The system includes software processes operating over the network to execute purchase, authentication and downloading aspects of a transaction.

Abstract: According to the present invention a modular trial instrument having opposed ends for sizing of an implantable orthopedic prosthesis is provided. The instrument comprises a head component located at one end of the trial and having at least one connection portion and a stem component located at the other end of the trial defining a longitudinal axis. The stem component includes a tip portion and a connection portion longitudinally opposed from the tip portion. The tip portion of stem component is received in the medullary canal of a bone. It will be apparent to those skilled in the art that the trial instrument can be used for sizing an implantable orthopedic prosthesis for any limb, for example, a humerus or a femur.

Abstract: A mounting assembly for a plurality of panel board electrical buses which are disposed within a panel board housing, said mounting assembly which includes a mounting plate and a bus insulator assembly. The mounting plate has a front side, a back side and a plurality of bus insulator assembly pin openings therethrough. The mounting plate is sized to fit within said panel board housing. The mounting assembly further includes bus insulator assembly pin openings located within conical depressions on said mounting plate. The bus insulator assembly has mounting pins. When assembled, the bus insulator assembly mounting pins pass through the bus insulator assembly pin openings.

Abstract: A final fixation assembly includes a rod receiving ring for receiving a portion of a rod therein and including a compressible insert for receiving a portion of the rod therein in a noncompressed condition and conforming allowing the portion of the rod to fixedly lock the portion of the rod therein in a compressed condition. The rod receiving ring maintains the insert in the compressed condition when the insert is seated therein.
